Pervaporation Membrane Module Design with Simulation

J. Boon [1], H. Heuver [2], F. Velterop [2], H. van Veen [1], A. de Groot [1],
[1] ECN, Petten, The Netherlands
[2] Pervatech, Rijssen, The Netherlands

Pervaporation is the selective evaporation of one component in a liquid mixture using a membrane. HybSi pervaporation membranes consist of porous ceramic support tubes with a thin selective layer on the inside or feed side. Modules for 7 and 19 membrane bundles (surface area up to 2.0 ...

Simplified CFD Modeling of Air Pollution Reduction by Means of Greenery in Urban Canyons

S. Lazzari [1], K. Perini [1], E. R. di Schio [2], E. Roccotiello [3],
[1] University of Genova, Dept. of Sciences for Architecture, Genova, Italy
[2] University of Bologna, Dept. of Industrial Engineering, Bologna, Italy
[3] University of Genova, Dept. of Sciences of Earth, Environment and Life, Genova, Italy

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the ... Read More

Modeling Ex Vivo Microwave Hyperthermia of Different Biological Tissues

[4] University of Parma - Department of Information Engineering, Parma, Italy

We describe the thermal modeling of a crate hosting boards with Associative Memories (AM) designed for the Fast Tracker Trigger (FTK) system of the ATLAS detector at the CERN Large Hadron Collider. FTK is a highly paralleled hardware system designed to provide global tracks reconstructed ... Read More

Finite Element Modeling of an Aluminum Tricycle Frame

B. Chine' [1], A. Rodríguez [1], J. Alberto Ramírez [1],
[1] School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

As a sustainable urban transport system, the tricycle might represent an adaptive mobility vehicle used to transport people and bulk load. This transport system must warranty the security of its end users, then experimental and modeling works are very useful tools in order to evaluate ... Read More

Numerical Simulation of Bank Protection Structure Deformation due to River Level Fluctuations

R. Hu [1], Y. Xing [1],
[1] School of Earth Science and Engineering, Hohai University, Nanjing, China

In this study, based on a bank protection structure engineering at Yangtze River, a 2D water-soil coupling model is established, in which the influence of water level fluctuation on groundwater seepage and soil shear strength is considered. According to the water level measured data of ... Read More
